Chapter 3: Introduction
3.1. Function of the Moisture Analyzer
•
•
The primary function of the device is to make precise measurements that allow the user to determine the
moisture content of various materials using the principle of thermo-gravimetric analysis – mass loss of a
sample caused by rapid drying due to an increase in temperature.
Drying and configuration parameters such as the drying time, temperature, and sample weight, are
determined by the user. Parameter should be established by evaluating the physiochemical properties of a the
sample which will undergo the analysis. Optimum configuration parameters are also often derived through
trial-and-error.
3.2. Good Practices and General Rules
•
•
•
•
•
•
•
•
•
Larger samples take longer to dry, but produce more accurate results. When accurate results are required,
try to stay in the 5 to 15 gram range. Use the Drying Chart feature to help in optimizing the Sample Size,
Drying Time, and Temperature.
For uniformity of results, it is better to set the Drying Time for a little longer rather than shorter.
Lower temperatures take longer, but produce more uniform results in many materials. This is especially true
if thermal decomposition is encountered in which added moisture is driven off as drying continues because
of decomposition.
Prepare the sample properly. This includes: obtaining uniformity of initial weight, leveling the sample,
using a glass fiber disc with fluid samples or samples that produce fluids when heated, and avoiding
carbonization of the sample when possible (lower heat helps).
Prepare the sample quickly and get it into analysis before its moisture content is altered by its surroundings.
The more samples tested, the better the statistical reliability of the results.
If solvents are required, be very careful of the vapors produced—they can be flammable or even explosive.
Safety first!
Keep the Analyzer clean, keep the area around the Analyzer clear, calibrate the weighing unit periodically,
and test the unit for moisture accuracy using the Sodium Tartrate Dihydrate chemical standard whenever
problems are suspected (or periodically).
Above all, remember the Drying Chamber can run at high temperatures, so use caution whenever opening
the cover or handling sample pans. The internal surfaces retain heat for some time.

- 12 -
Instruction Manual – ATS / BTS Moisture Analyzers
8.3. Understanding drying parameters and settings
1. Drying Temperature - maximum drying temperature which will be used to perform moisture analysis.
2. Mode - The analyzer can be used in two drying modes:
Short Mode (Automatic): Drying is terminated when the mass loss between successive samples
taken during the moisture analysis (Sample Quantity) is smaller than the threshold value of 2mg.
Time Mode – Drying is terminated when user defined time (Drying Time) is reached. The Drying
time can range from 1second to 10 hours.
3. Calculation – results can be calculated and displayed using one of the three formulas:
W [%] = m0 – m/m0 * 100%, where moisture is determined in relation to initial weight
W [%] = m0 – m/m * 100%, where moisture is determined in relation to current weight
W [%] = m/m0 * 100%, where current weight is determined as a percentage of sample weight
Where: m0 = initial (wet) weight, m = current weight, and W [%] = moisture as a %
4. Samples Quantity – used and required when operating the analyzer in the Short Mode. The analyzer uses the
setting to check whether the mass loss taken between the samples is less than 2mg. Higher number of
samples taken allows for a more accurate determination.
5. Sampling Interval – time separation between each sample taken. This setting is used when operating the
analyzer in the short mode and it can be optionally used in the time mode when tracking the progression in
mass loss of the sample i.e. transmitting the sample mass to a printer or a PC.
- 13 -
Instruction Manual – ATS / BTS Moisture Analyzers
6. Drying time – defines the total drying time for a sample when operating the analyzer in the Time Mode.
When using the analyzer in the Short Mode the drying time should be set to 10 hours.
7. Drying Profile – one of four drying profiles can be selected when performing moisture analysis. Selecting a
drying profile allows to optimize the analysis by adjusting the drying progress to the physical properties of
the sample. Although most samples can be accurately analyzed with the standard profile, other may require
a slow, stepping, or fast temperature progression. I.e. samples prone to natural evaporating or thickening
may require the use of a slow or step profile. Samples that are resistant to temperature may require the use
of a fast profile. Before selecting a profile perform trial analysis and tests to make sure the results are
accurate and the sample responds to the selected profile appropriately.
8. Settings storing – allows select one of 20 memory location for storing configured parameters. This feature is especial
useful when analyzing samples that require different drying parameters.
- 14 -
Instruction Manual – ATS / BTS Moisture Analyzers
Chapter 9: Preparing the Sample
1. A sample of a given substance must be a good representation of the material. Drawing and preparing a sample is a
very important process as it may affect the repeatability of measurements. The most common method of
homogenizing a sample is mixing. Another method is to draw a few samples from different but specific points in a
substance and calculate an average value, or to draw a few samples from different points in a substance, mix them,
and draw a sample from the mixture.
Note: The sampling method depends on the type of research being performed. In quality control, usually many
representative samples are analyzed. In production control, it is enough to confirm sampling repeatability.
2. When preparing a sample, it is important the sample does not absorb moisture from the surrounding environment –
thus preparation time should be as short as possible.
Note: If necessary to analyze more than one sample at the same time, the samples should be placed in separate
hermetically sealed plastic bags or containers. Make sure the sample does not lose moisture while it is inside the
container (the container or plastic bag should not have much air in it).
3. Tools and instruments used in the preparation process may affect measurement accuracy. Do not use tools that
transmit heat as this can cause the sample to lose moisture before the actual analysis. Use only special grinders and
mixing instruments. When drawing a sample from a liquid containing solid materials, use a glass mixer, spoon, or
magnetic mixer.
4. To analyze moisture content, place the sample on the disposable pan provided with the unit and place it in the dryer
chamber. Using disposable pans helps to avoid the false results that may be caused by the residue left from previous
samples.
5. A sample should be always thin and distributed uniformly throughout the pan so that the heat penetrates equally all
over the sample and dries the entire sample effectively.
A sample that is thick or unevenly distributed will cause the top surface of the sample to be overly dried and possibly
burned while the sample underneath the top surface remains wet. This may result in the sample being burned or the top
surface hardening which will make the analysis more difficult as well as inaccurate.
A sample should always be placed in uniform layers measuring 2 to 5mm in thickness and weighing 5 to 15g, depending
on the substance. When drying liquids, pastes, or substances that may melt or lose liquid during the drying process, the
use of glass fiberfilters is recommended as filters ensure equal liquid distribution. When solid materials are being dried, a
glass fiberfilter will prevent the sample from burning.

Chapter 10: Performing Moisture Analysis
After configuring all of the necessary parameters and preparing the sample, you may begin your moisture analysis by
following the steps below:
1. Open the Drying Chamber.
2. Using the Pan Handle, place the Disposable Pan on the Pan Support.
Note: Be sure the Pan Handle is not touching the Pan Shield.
3. Press the T key to Tare the Disposable Pan.
4. Place the sample on the Disposable Pan. After the Tare has been performed, the Disposable Pan can be removed from
the Pan Support by using the Pan Handle to evenly distribute the sample.
Note: Make sure the sample is evenly distributed on the Disposable Pan.
- 16 -
Instruction Manual – ATS / BTS Moisture Analyzers
5. Close the Drying Chamber.
6. Press the START key. The unit will indicate on the display that Heating is in progress. The moisture content of the
sample will be displayed as a percentage (%). During the analysis, in addition to the result, the display will indicate the
Drying Chamber Temperature, the present weight of the sample, the elapsed time, and the initial weight of the sample.
Important Caution Note: Do not touch the top surfaces of the Moisture Analyzer’s Drying Chamber or any internal parts
either during or soon after use. As the parts and surfaces will be very HOT, allow adequate time for the unit to cool. Be
sure to read and follow all Caution Procedures listed in Chapter 1.
7. When the analysis is finished, “END” will be displayed in the lower right corner of the LCD. The Final result will
remain displayed. To clear the result and prepare the unit for the next analysis, press the key STOP.
Important Note: Always use the forceps supplied with the unit when handling a used Disposable Pan.

Instruction Manual – ATS / BTS Moisture Analyzers
Chapter 11: Determining Drying Parameters for Unknown Samples
Optimal drying parameters for a sample can be easily obtained by performing trial-and-error analysis. The objective is to
establish an ideal Drying Temperature for the sample, as well an optimal Drying Time, and Sample Size.
Drying Temperature - An ideal Drying Temperature is such that will allow the analyzers to completely dry the sample in a
reasonable amount of time (with unnecessarily delaying the analysis), but won’t burn the sample. Burring or introduction
of combustion will always result if an inaccurate result. Even discoloration can be a sign of combustion.
Drying Time – total drying time must be long enough to completely dry the sample. If drying time is too short, moisture
will remain in the sample after the analysis is terminated therefore resulting in an incomplete result.
Sample Size – the size of sample must be an adequate statistical representation of the substance or matter which is
analyzed. A sample should always be placed in uniform layers measuring 2 to 5mm in thickness and weighing 5 to 15g,
depending on the substance. Large samples will require a longer drying time.
To perform trial-and-error analysis it is recommended to use the analyzer’s graph plotting feature (Drying Chart). The
graph will assist in determining optimal drying time.
11.1. Activating the Drying Chart
1.
Press the Menu key and use the navigation keys to select option 3 (Drying Options).
2.

3. Perform a trial analysis with the above recommended settings as well the Drying Chart feature enabled.
Warning: Never leave the analyzer unattended while performing trial analysis.
11.3. Interpreting the Trial Analysis, making adjustments, and finalizing the settings
Drying Time can be derived by observerving the Drying Chart on the analyzer’s display while the trial analysis is
in progress. The sample is dried when the slope of the drying chart flattens. The actual drying time should be
defined with a reserve, taking into consideration differences in the weight of successive samples.
Drying temperature can be derived by carefully observing the sample inside of the drying chamber while the trial analysis
is in progress. Through the chamber peek glass observer the sample to make sure it is not burning or discoloring.
If discoloration occurs or if the sample begins to produce smoke terminate the analysis by pressing STOP. Signs of
combustion indicate that the current temperature is too high. Lower the temperature and perform the analysis again using
a fresh sample.
If it is obvious that drying is taking too long and moisture in not evaporating quickly enough, terminate the drying,
increase the temperature, and perform analysis again using a fresh sample.

Chapter 13: Temperature Correction and Adjustment
The analyzer’s temperature sensor can be recalibrated and adjusted to measure temperature based on readings derived
from an external temperature probe or thermometer. Temperature calibration and adjustment should be performed only if
the sample must be dried under strictly controlled temperature conditions, when temperature accuracy is of an essence in
order to perform accurate drying. The external thermometer or temperature probe should be manufactured to highest
standards and accuracy with a tractable certificate of calibration.
Two temperature readings (T1 and T2) must be taken to record the analyzer’s temperature (Device temp.) and its
equivalent values measured by external thermometer (Control temp.). T1 and T2 values should be based on the lowest and
highest temperature settings that will be used in the analyzer. T1 and T2 correction parameters must conform to the
following conditions:
T1 and T2 < 160 oC
T2 - T1 > 25 oC
T2 > T1
Maximum correction allowed: 20oC
13.1. Installing the external temperature probe
Insert the external temperature probe (1) through the opening located in the analyzers venting grill. The probe should be
lowered to the same height as the analyzer’s temperature sensor (3). To adjust the height of the probe use an adjustment
sleeve (2) that will keep the probe in position. To calibrate the analyzer’s sensor in relation to temperature of a specific
sample, lower the probe as low-as-possible but without touching the sample.

Chapter 19: Testing the Analyzer with Sodium Tartrate Dihydrate
Important: Always wear protective goggles over your eyes and rubber gloves when handling Sodium
Tartrate Dihydrate. Protect your mouth by wearing a dust mask.
Warning:
If inhaled, Sodium Tartrate Dihydrate may cause mild irritation to the respiratory tract. If the chemical comes
in contact with skin or eyes, it may also cause mild irritation. If swallowed, a large dose may cause
gastrointestinal disturbances.
First Aid:
•
•
•
•
If inhaled, immediately move to an area with sufficient fresh air. Get medical attention for any
breathing difficulty.
If ingested, drink several glasses of water or milk. If a large amount was swallowed, get medical
advice.
If skin contact occurs, wash exposed area with soap and water. Get medical advice if irritation
develops.
If eye contact occurs, wash eyes thoroughly with water. Get medical advice if irritation develops.
Sodium Tartrate Dihydrate is a chemical compound that can be used as a standard to check the accuracy of the Moisture
Analyzer. When the chemical is heated to 150°C, it undergoes a chemical change that releases moisture (theoretically
15.66%) so the chemical should lose 15.51% to 15.81% of its weight. The “m0 – m/ m0 * 100%” formula will show the
results directly. If the chemical has been stored at elevated temperatures or subjected to mechanical abuse, the results may
vary. To test the analyzer perform the following steps:

•
•
•
•
Before cleaning the unit or replacing halogen bulbs, always unplug the power cord from the electrical outlet.
Before performing any maintenance on the unit, make sure all parts and surfaces of the Analyzer have cooled.
Use a soft, lint-free, slightly damp cloth to clean the Analyzer.
Wipe the unit gently. Do not allow any liquid to enter into the Analyzer’s weighing or drying mechanisms.
Do not touch the temperature sensor (see parts description).
Do not apply extensive pressure to the LCD display.
Do not use chemicals especially benzene when cleaning the surface. Corrosive chemicals may damage the finish.
Alcohol may be used only to clean the scale’s stainless steel pan support or the pan handle.
To prolong the life of the halogen bulbs, be sure the bulbs are clean and free from fingerprints. Even a small amount
of oil from your fingers can cause the bulb to break when it is turned on.
Replacing the Halogen Bulb
Replace the halogen bulbs when they are defective or when you sense that drying is taking more time than usual.

Warning:
Before replacing the halogen bulb, avoid electrical shocks by unplugging the power cord from the electrical outlet.
Make sure the rated voltage of the new halogen bulbs is correct for the voltage of the power supply,
Handle the old bulb with care to avoid cracking. Broken glass may cause injury.
Never touch a halogen bulb with your bare fingers.
Always wear gloves when handling a new bulb. Even a small amount of oil from your fingers can cause the bulb to
break (or shorten its life) when it is turned on.
If a bulb is touched, before being used it may be cleaned with a lint-free cloth.
When replacing the bulbs in the Analyzer, avoid touching the temperature sensor
To replace the halogen bulbs follow the steps below:
